Unable to complete Detectives: Too Many Turtles

Brief bug summary: Upon accepting the quest [Stellar Detectives] Too Many Turtles and watching the initial cutscene, my character is transported to an empty room with a single portal and two platforms. These are the only objects in the room. Several text boxes appear, detailing a seemingly unrelated description of a spacesuit and how to use it. (See attached images.) The portal does not respond to any of my inputs, trapping me in the room until I exit the game or the 20-minute timer runs out.
